The Real Time Streaming Protocol (RTSP) is a network control protocol designed for use in Multimedia Session Control Working Group (MMUSIC WG) of the Internet Engineering Task Force (IETF) and published as RFC in RFC Real Time Streaming Protocol (RTSP) (Q). request for comments publication.

Within RTSP, redirection may be used for load balancing or redirecting stream requests to a server topologically closer to the client.

Indicates that the client is willing to accept a media stream that has exceeded its expiration time. As an example, assume that video frames are generated every 40 ms. The server is free to use a blocksize which is lower than the one requested.
The presence of an Expires field does not imply that the original resource will change rrc cease to exist at, before, or after that time. For audio, it may time-scale the audio while preserving pitch or, less desirably, deliver fragments of audio. To do this, the client may include the only-if-cached directive in a request.
The bandwidth available to the client may change during an RTSP session, e. A negative value indicates reverse direction. The mode parameter indicates the methods to be supported for this session.
It is interpreted according to [H The layers are sent to consecutive addresses starting at the destination address. In other projects Wikimedia Commons. In the worst case, servers rff send back: This information may also be available through SDP. Unsourced material may be challenged and removed. Only the start time of a media unit such as a video or audio frame is relevant.

The value of the timestamp is of significance only to the client and may use any timescale. July Learn how and when to remove this template message. Serious operational problems may occur, however, efc these transformations have been applied to streams intended for certain kinds of applications. This is disallowed 23326 that presentation by the server.
That is, the cache must do an end-to-end revalidation every time, if, based solely on the origin server’s Expires, the cached response is stale.
Real Time Streaming Protocol
This parameter is only valid for unicast transmission. If the Range header is given in a time format that is not understood, the recipient should return ” Not Implemented”. The timeout is measured in. The interleaved parameter implies mixing the media stream with the control stream in whatever protocol is being used by the control stream, using the mechanism defined in Section See example in Section This allows clients to gracefully deal with packets when seeking.
This keeps the syntax of the Transport header simple and allows easy parsing of transport information by firewalls.

The number of multicast layers to be used for this media stream. Ranges are half-open intervals, including the lower point, but excluding the upper point. This status code is also to be used if a request attempts to use a method not indicated during SETUP, e. Any 226 request must contain the same sequence number as the original i. Since other processes on the server may be consuming storage space simultaneously, a client should take this only as an estimate.
It identifies the synchronization source to be associated with the media stream. If max-stale is assigned a value, then rvc client is willing to accept a response that has exceeded its expiration time by no more than the specified number of seconds.
The block size MUST be a positive decimal number, measured in octets.
Here’s an example of how a multi- stream server might expect a single-stream file to be served: The default value for the “lower-transport” parameters is specific to the profile. This enables the server to keep a single storage handle open easily.
